An alkene having molecular formula C8H12 on ozonolysis yields glyoxal and 2, 2-dimethyl butane-l, 4-dial. The structure of alkene is
Which of the following will give Cannizzaro reaction?
CH3CHO
CH3COCH3
(CH3)3C-CHO
CH3CH2CHO
C.
(CH3)3C-CHO
Aldehydes containing no -H atom give Cannizzaro's reaction. (CH3)3C-CHO does not contain -H atom, hence it will give Cannizzaro reaction.
